HDMI issues at GDC? Or simply no cable?

The PS3 dev kits on display at GDC apparently skipped the HDMI connection
for some of their demos, casting doubt on how far along Sony's come with its hardware and digital standards
compliance.

During GDC, Sony brought along a few PS3 demo units to show off audio and video, which TG Daily
spied from a distance. As you can see above, the PS3 graphics demo unit used a standard AV Multi-Out connector while
the "two HDMI ports right below the AV Multi-Out port were unused." TGD apparently offered to lend Sony
officials an HDMI cable of their own to connect to the system, but they were turned down.

Of course, there's
also a conflicting pic which Chris Grant took for us on Joystiq Central that seems to show that very HDMI connection
being used, probably with another unit. (Scroll down to the second pic here to see it.) So what's the real story?
Was Sony lacking enough updated HDMI 1.3 hardware and/or 1.3-compatible TVs to show off the HD goods, or were they
simply short on cables? Maybe their budget was a bit tight for GDC (what with Phil's focusedkeynote and
abundance of GDC sessions from Sony), so hopefully we'll see everything hooked up nice and tidy for E3.
